How to see how long an IP has been inactive
7 posts · Closed
We mainly use ping sweep to help us identify reserved IPs that are no longer active, mainly as a result of devices being moved, upgraded etc., and no one telling us. We would like to ping a range/scope for, say, 8 weeks, and remove devices we get no reply from, leaving us with reserved IPs that are no longer needed, so we can then release them from reservation and re-use them. Is there any function for being able to see how long an IP has been inactive for?
There no built-in fictionality for this, but I guess we could add some kind of Network History tool. It would list MAC addresses, IP addresses, how many times they were seen and when they were seen last. More statistics and details could be added later to this tool. Does this sound like what you are looking for?
Yes, that would be fantastic! Being able to see when an IP was last seen active allows us then to consolidate unused IPs and release them from reservation. You can never have too much info!
Thanks
I've found that this is currently sort of possible. Going through the settings I was able to turn on viewing of inactive devices and Last Scan does display how long it has been offline. Would be nice to make this more prominent, perhaps the ability to change the font colour?
Sure, that may be a way to do it. You can fully customise the font and background, even conditionally. Here is a sample of what it can look like:
Cheers for that... that will work nicely!
I have requested some quotes, but seen nothing yet. I'll chase this up via Contact Us.
Network history sounds great too.
